upphafaðar
Upphafaðar is an Icelandic term that translates roughly to "original cause" or "prime mover." It is a concept that appears in philosophical and theological discussions, particularly when considering the origin of the universe or existence itself. The idea of an upphafaðar suggests there must be a fundamental, uncaused cause that initiated all subsequent events and phenomena. This is often posited as a necessary being, something that exists by its own nature and does not depend on anything else for its existence.
The concept of an upphafaðar is a common theme in cosmological arguments for the existence of God.
